The only auto-correct PSSE can do is to net in-service generators with missing generator model.

There is no problem to write a script for auto-correction. I have done something similar that updates the governor limits based on Pmax in saved case.

However, for exciter limiter violations I prefer to solve it manually, since almost always the problem lies in wrong load flow data, e.g., wrong Q-limits, solved without Q-limits, wrong Mbase, etc. For a correctly initialised exciter model, Emax should be well above the calculated field voltage (Efd).
